Gemini Notebook is a powerful literature review assistant tool, allowing you to quickly get a shallow understanding from a large collection of papers and identify key concepts. However, it is also suitable as a long-term research partner because you can ask questions about all PDFs simultaneously, and the results refer to specific passages within these PDFs, enabling a very deep semantic search and an easy way of double-checking if the AI made any mistakes. This in-depth review evaluates the latest version of Gemini Notebook and how researchers can use it to accelerate the literature review.
Learn which tools can speed up your research: This free 21-day email series introduces you to a range of academic tools and how they work together to speed up the time needed for a literature review. Most of these tools have been around for less than a few years, some use AI. Knowing them gives you an almost unfair productivity advantage for your research.
In recent years, AI tools have become more than just “assistants.” They’ve started to reshape how we actually do research. Among these, Google’s Gemini Notebook has carved out a space for itself as a genuine academic partner, not simply another summarisation engine.
What is Gemini Notebook and Why You Should Use It
Gemini Notebook is Google’s tool to analyse large bodies of information presented as a collection of various PDFs, URLs, or YouTube videos. Free members can analyse up to 50 sources (500.000 words each), while pro members can upload up to 300. It provides additional tools to extract the information through: Audio and video overviews, mind maps, timelines and customised reports. This allows you to tackle any complex problem (like a literature review) through various angles. Surprisingly, the free version is often sufficient for students working on an assignment.
Importantly, every query overview or summary can be scoped to select all or only a few sources from your database. Let’s look at the different types of summaries and information extraction capabilities Gemini Notebook offers within its “Studio” (top right box in the image).
Mindmaps: Using Gemini Notebook to Start a Literature Review
Mind maps identify recurring topics within your sources and display them as a mind map. This is particularly useful for students and young career researchers dealing with a novel topic. You can use these topics to either query Gemini Notebook for more information, or use them as a guideline on how to take great academic notes.
The reason why I think mind maps are so helpful is that they provide a very high-level overview of your topic, which allows you to find research gaps. If you click on a subtopic in the mindmap, Gemini Notebook will first generate an AI summary of that particular subtopic, which gives you a little bit more detail on what it is about. That AI overview will contain references to the individual papers that you can click on to get a fine-scale overview by jumping directly into the paper. These three levels of detail make it very easy to navigate a large body of knowledge. I made a short video to showcase you this functionality:
These three levels of detail are displayed side-by-side: you have your mind map on the right, you have a medium-scale AI chat in the middle, and you have a fine-scale deep dive into the PDF on the left. Keep in mind that mind maps are generated based on the sources you select, and they will not always produce the same results. Running the mind map feature multiple times may sometimes yield different overviews that are more or less useful to you.

Audio & Video overviews: Getting familiar with your field
When Gemini Notebook first came out in 2024, audio overviews would tend to startle people because of their lifelike podcast quality: Two hosts discuss highly complex academic topics in a nonchalant, conversational tone. They agree with each other, interrupt each other and sound like real humans. Here is an example:
Recently, Gemini Notebook introduced a similar concept but added a PowerPoint presentation to create videos instead of audio. Here is how the result looks for my Gemini Notebook notebook, which explores different algorithms used by ecologists to measure the areas of leaves.
The video is engaging, well-designed, and generally fun to watch.
In my opinion, the downsides of both overviews are that they can be somewhat unfocused for academic research, missing specific topics that might be relevant or niche-related questions. Therefore, I find them primarily relevant if you want to get an overview of a topic that is entirely new to you. If you’re a senior academic looking to find answers to complex, specific questions that may not even be the main topic of the papers you uploaded, you will not gain much from the overviews. However, even then, just generating this overview and listening to it while you go to the gym or walk your dog is a great way to catch up on a few ideas without a large time commitment.
Timeline: Identify Developments & Prominent Authors
The timeline analyses your sources and the content within to create a timeline of how knowledge developed over the years. This can be particularly useful for individuals studying philosophy, history, or politics, or for life scientists writing a comprehensive synthesis on the evolution of questions over extended periods. In my example here, the timeline begins with a paper published in 1903, a time when the term “ecology” was not yet widely used.
At the bottom of your timeline, you will find a cast of characters which outlines the main authors who wrote the papers in your source collection and the people mentioned in these papers. Particularly, that feature makes it apparent how useful this can be when analysing historical or political information, or working on novels, interview transcripts and so on.
Reports: Customisable Information Extraction
Offer you a way to provide a custom prompt to generate a synthesis on a question that you have regarding all (or some) of your sources. For instance, if you have a paper collection on climate change in general consisting of hundreds of papers, you might want to get a report on exactly how elevated CO2 levels influence plant growth, or you could query the same collection of papers and ask about how the climate is going to change in the next hundred years. Generating multiple reports on the questions you are interested in can help you find an answer to your question as well as identify the key papers that are related to this question for further study.
In the next section, I have combined several Gemini Notebook prompts that may be useful when working on your literature review.
Top 5 Gemini Notebook prompts for your literature review
Don’t think of Gemini Notebook as simply an AI that summarises PDFs. It can do much more than that and help you find logical contradictions, gaps, and trends in your research field. Keep in mind that, while AI is surprisingly good at synthesis, it may not always provide complete answers and they might not always be correct. This is why it is essential always to verify the sources that Gemini Notebook cites in its reply and double-check using your own judgment.
1. The “Gap Hunter” Prompt
When you’re new to a topic, knowing what is already known and what is at the forefront of academic research can be a challenge. A clearly identified research gap can help you make your paper more impactful and relevant. Here is the prompt:
You are an expert research mentor specializing in [discipline X]. From the following sources, identify at least three categories of research gaps: (a) methodological, (b) theoretical, and (c) empirical/contextual. For each category, write: (1) a one-sentence description of the gap, (2) an example paper or finding that highlights the gap, and (3) a suggested research question. Present as a table with citations.
2. The “Methodology Deep Dive” Prompt
When discussing limitations over fields and previous shortcomings, it is important to know what has been done insufficiently and point that clearly out in your introduction and discussion sections. This prompt can help:
Analyze the methodological weaknesses and recurring challenges in the field of [discipline/topic X]. From the provided sources, extract 4–6 common issues (e.g., small sample sizes, weak controls, measurement biases, reproducibility concerns). For each issue, explain (1) how it appears in multiple papers, (2) why it matters for validity or generalizability, and (3) what solutions or best practices could address it. Conclude with a short synthesis: which weaknesses most seriously limit progress in [topic X], and how future research could overcome them.
3. The “Recurring Topics Extractor” Prompt
When diving into a new field of research, it is essential to understand the concepts that researchers are studying and how they relate to one another. Each idea can later become a note in your note-taking vault, but identifying them can be time-consuming, especially for young career researchers. This prompt can help you determine the key topics right away and streamline your note-taking and reading process:
From the provided papers on [topic X], identify the 5–10 most recurring themes, concepts, or research questions. For each theme, provide: (1) a short definition in your own words, (2) which papers mention it (with citations), and (3) a one-sentence summary of how it is treated (e.g., debated, assumed, tested). Present the output as a table or structured bullet list I can use as a basis for targeted note-taking.
4. The “Trend Detection” Prompt
When writing a literature review, it is incredibly useful to understand how the field has developed in recent years, which allows you to place your research more clearly and will help polish the introduction, making it more impactful and your paper more relevant. Try out this prompt:
Analyze the provided collection of papers on [topic X]. Identify 5–7 major trends over time (e.g., rising methods, shifting focus areas, new theoretical debates). For each trend, provide: (1) a short description, (2) the approximate timeframe when it became more frequent, (3) example papers or citations, and (4) whether the trend appears to be increasing, stable, or declining. Conclude with a short synthesis of what these trends suggest for the future of research in [topic X]. Present results as a timeline-style bullet list.
5. The “Contradiction Finder” Prompt
A hallmark of a good literature review is identifying where insights lead to contradictions. For instance, we know that elevated carbon dioxide levels, related to climate change, will decrease biodiversity because species struggle with the hotter climate. However, there are other species that are well-adapted to hotter temperatures and may benefit from the elevated CO2 levels. This forms a contradiction that, at least in ecology, is at the moment an open question. A literature review focusing on this contradiction would be a meaningful and impactful research paper relevant to a global audience and, therefore, publishable in a prestigious journal. Here’s a prompt that can help:
From the provided papers on [topic X], identify major contradictions or conflicting findings. For each contradiction, provide: (1) the specific claim or result from each side (quoted or paraphrased with citations), (2) possible reasons for the disagreement (e.g., differences in method, sample, context, or assumptions), and (3) a short note on what kind of further evidence would help resolve the conflict. Present as a structured bullet list or a two-column table contrasting the opposing findings.
Gemini Notebook Alternatives
One prominent alternative to Gemini Notebook is Anara, a tool that specialises in analysing large bodies of academic knowledge. Anara is made specifically for academics and has multiple other features that might be useful and go beyond what Gemini Notebook can do.
If you are looking for a summary generator rather than a multi-purpose tool, SciSummary could provide a good alternative. You can generate contrasting summaries and summaries related to specific topics:
If you have a ChatGPT subscription, using ChatGPT projects could also be a viable alternative to Gemini Notebook, especially if you want to focus more on the writing aspect rather than the synthesis:
Gemini Notebook vs Gemini
Gemini Notebook runs on Gemini, which means that if you have a Gemini subscription, you also get a Gemini Notebook subscription. While Gemini is a multi-purpose chat tool, developed by Google, Gemini Notebook specialises in extracting information from a large collection of various sources. Gemini, on the other hand, has capabilities like internet search or deep search, allowing you to find information rather than process it. Gemini Notebook is also not optimised for academic writing, while Google’s Gemini, like ChatGPT, can be customised to create excellent academic writing. In fact, the combination of Gemini and the PaperPal Reference Manager can create a compelling workflow that I explain in the Effortless Publishing course:
ChatGPT (Projects) vs Gemini Notebook
ChatGPT projects, like Gemini Notebook, allow you to upload multiple files that the AI will work on to generate a synthesis and query these papers. However, as ChatGPT is a multi-purpose tool, you don’t have specific features like deep citations, mind map generations, or timelines. On the other hand, ChatGPT is better at academic writing, has a memory allowing it to refer to past conversations, and can be customised with instructions to provide answers in a more succinct, opinionated, or otherwise different way.

Summary: Is Gemini Notebook worth it for literature reviews?
Gemini Notebook is a great partner to get started on any literature review because you only need to provide a few papers to start extracting information with various pre-built tools, like a mind map, a timeline generation, or customised reports. It provides references that point directly to passages within PDFs, allowing you to double-check the AI output. Its main weakness is that it cannot search for other papers that might be relevant to your lit review and, therefore, is primarily a tool for information extraction and synthesis that you will need to supplement with tools like Litmaps or Consensus for finding relevant papers. I explain more about these tools and the Effortless Literature Review course.
Some of the features that Gemini Notebook offers (such as an audio or video overview) might be more flashy than useful for an experienced academic, but can at least be entertaining for young career researchers or people who are entirely unfamiliar with the topic they’re about to study.
Gemini Notebook can also be an excellent partner during the synthesis stage of your literature review, as it allows you to ask very specific, nuanced questions to a subset of your papers, providing a flexible approach to information extraction and synthesis.
Gemini Notebook offers a generous set of features, even in the free version. However, with a Pro subscription, you also gain access to Google’s Gemini (as an alternative to ChatGPT), extended storage in your Google Drive, and many other benefits, making it an attractive package deal for academics.
